Creda 34944
Yesterday, I called to a 25 year old double oven that has been in storage for most of its life. It’s in prestine condition but blows the earth leakage trip when turned on.
I advised the customer over the phone that the only sensible thing to do would be to replace all the elements as they are likely to have drawn in moisture over the years and this will show as a low insulation resistance.
I called yesterday to fit the elements. Two grill elements 6224597, base element.6224630 and two main oven side elements 6224597 (these elements where marked as ELE3799 but are repackaged genuine parts) After putting it all back together, I left it to get to temperature and the damn thing tripped the RCD again. Totally confused, I took the appliance out again to meggar it only to find that BOTH of the new main oven side elements had failed when they got hot!
I would imagine that, as the machine is virtually an obsolete model, these elements have been sitting in a warehouse somewhere for years.
My question is :- When I replace the elements again, is the same thing going to happen? Is there a way for me to test them before fitting them as they only failed when reaching temperature.
Would it make sense to cook them in my oven at home for a few hours prior to going to the call?

Re: Down to earth cooker elements
We used to have this problem when I worked for creda with there Gen Elements. We either wired them up at home ( In garage) without an earth and run them for 10 Mins or if you could ensure safety remove the earth fron the cooker and run all the elements till they dried out. Almost always worked.

I think you will find that they are not repackaged genuine parts.
Re: Down to earth cooker elements
Hi Bob,
Yep been down that road, I normally run them on the bench without the earth connected to try and dry them out if I think its a dodgy one. Always found “old stock” elements not much cop.

using a Pat tester with a mains plug and three croc clips on the end is ideal as you cant test it for low insulation when its been running and is still hot, saves the 😳 of tripping customers Rcd again and them thinking that you dont know what ya doing 😉

Re: Down to earth cooker elements
Had similar problem with my own Creda panel heaters i bought as a job lot out of a cold garage. The shiniest unused one trips after 5 mins. After running elements for thirty minutes in vice (No earth) 😯 and not touching them whilst plugged in it has worked fautlessly for months. Hope this helps.

Re: Down to earth cooker elements
Yes indeed these replacement element insulation problems go way back for me to the old Moffat days. (1970’s) 😯
Almost always affected the side or bottom elements and rarely the grill element. What we did then (no RCD’s in those days, just lousy Megger readings and tingling sensations when you touched the oven door, gave the game away :zap: ) and I have done since whenever I get problems is simply to disconnect the earth for 15 minutes or so whilst it heated up nicely. Meggar it after and reconnect the earth again :tup:
Much better than bu&&ering about sticking them in the vice or whatever 😉 As very often using that method can distort the element anyway as they are not in their fixings. They will absorb more damp when they cool and by the time you fit them, you’re back to square one again 🙄
Re: Down to earth cooker elements
The solid hotplates are also prone to this, especially in holiday homes. Money for old rope, 😉
Re: Down to earth cooker elements
Thanks everybody for your help.
These two elements were wrapped in corrogated card with an Electru part number on the outside. Inside they were in original Hotpoint/Creda packaging complete with Hotpoint part number sticker and the normal Hotpoint “alternative part” leaflet… Surprised me!
I only ordered them because the Gen ones were out of stock.
